Definitions

  • This invention relates to conveyors and more particularly to a multiple link conveyor capable of movement along straight or curved paths.
  • Conveyors formed of interconnected links are well known and have been constructed in many different forms to provide movement along an intended path.
  • One type of known conveyor as shown for example in U.S. Pat. Nos. 3,144,124 and 3,706,200, employs a plurality of links having knuckles interconnected by pivot pins to provide relative movement of the links in a normally vertical plane transverse to the conveyor plane.
  • Another type of multiple link conveyor known as a laterally flexible or sideflexing conveyor, is shown in U.S. Pat. Nos.
  • a further conveyor structure is the subject of U.S. Pat. No. 3,777,877 in which an array of palates are linked to underlying support plates by means of normally vertical pivots to provide for relative movement between palates and the support members about a normally vertical axis, the support members being hinged about a normally horizontal axis to permit banking of the conveyor.
  • a further conveyor type employs a ball and socket interconnection for the links, examples being shown in U.S. Pat. Nos. 3,344,905 and 3,370,331.
  • the present invention provides a conveyor comprising a plurality of identical interconnected modular links and capable of movement through straight and multiply curved travel paths.
  • the conveyor is operative to be moved in a curved path in the conveyor plane and in a curved path in a plane transverse to the conveyor plate.
  • Each link of the conveyor serves as an identical modular unit which includes linking ends pivotally connected to the linking ends of adjacent links for relative pivotal movement of adjacent links about a first axis.
  • Each modular link is composed of two sections which are pivotally joined at a position intermediate the linking ends for relative pivotal movement of the sections about a second axis orthogonal to the first axis.
  • the link sections are relatively pivotable in a first plane while the adjacent links are relatively pivotable in an orthogonal plane, and a conveyor composed of these interconnected links is therefore bidirectionally movable to provide versatile transport along various intended paths.
  • the link sections are pivotally joined for relative movement therebetween about a normally horizontal axis, while adjacent links are pivotally joined for relative movement about a normally vertical axis.
  • the link sections are pivotally joined for relative movement about a normally vertical axis, the adjacent links being pivotally joined for relative movement about a normally horizontal axis.
  • Sprocket teeth are integrally formed with the modular links for cooperation with vertical or horizontal sprocket wheels for transport of the conveyor in either plane.
  • a vertically disposed sprocket tooth of each modular link is disposed intermediate a pair of horizontal pivots, while a horizontally disposed sprocket tooth of each link is disposed intermediate a pair of vertical pivots.
  • the modular links may include a spaced array of upstanding ribs the upper surface of which defines a conveying surface.
  • the rib array of each link can be in meshed interdigitated relationship to a like array of ribs on adjacent links to provide an effectively continuous flat conveying surface even during movement of the conveyor through a cureved path in the conveyor plane.
  • the links are preferably molded of a high strength plastic material, while the interconnecting pins pivotally joining the links and link sections can also be of the same or a compatible plastic material.
